Environment
- OS: Ubuntu 20.04
- Compiler: gcc 9.3.0
To Reproduce
Please see below CMakeLists.txt to reproduce the error
set(CMAKE_TOOLCHAIN_FILE $ENV{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake)
cmake_minimum_required(VERSION 3.20)
project(example)
find_package(VTK)
add_executable(${PROJECT_NAME} ${PROJECT_SOURCE_DIR}/main.cpp)
target_link_libraries(${PROJECT_NAME} ${VTK_LIBRARIES})
In x64-linux, a simple mkdir build && cd build && cmake .. shows the below error
-- Searching for PEGTL
-- Searching for PEGTL - found target taocpp::pegtl
-- Found LibXml2: /home/jasjuang/vcpkg/installed/x64-linux/lib/libxml2.a (found version "2.9.12")
-- Configuring done
CMake Error in CMakeLists.txt:
IMPORTED_LOCATION not set for imported target "EXPAT::EXPAT".
-- Generating done
CMake Generate step failed. Build files cannot be regenerated correctly.
After some debugging, I realized that if I insert set(CMAKE_BUILD_TYPE "Release") the error will go away, e.g.
set(CMAKE_TOOLCHAIN_FILE $ENV{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake)
cmake_minimum_required(VERSION 3.20)
project(example)
set(CMAKE_BUILD_TYPE "Release")
find_package(VTK)
add_executable(${PROJECT_NAME} ${PROJECT_SOURCE_DIR}/main.cpp)
target_link_libraries(${PROJECT_NAME} ${VTK_LIBRARIES})
However, cmake config should not fail even if CMAKE_BUILD_TYPE is not set. Would appreciate if someone can fix this.
